FAN.

To all whom it may concern:

Be 1t known ,that I, HORACE E. WALKER, a

citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Fans; and I do hereby declare the followin to be a full, clear, and exact'description theinvention,

such as will enable others skilled in the art to which it appertains. to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of re erence marked thereon, which form a part I of this specification.

This invention relates to. new and useful improvements in fans and comprises various detail view of the fan blades;

Reference 'now being had to the details of the drawings by letter, A and B designate two handles connected together by means of "ing end B with teeth D along the end thereof designed to mesh-with the teeth E of a pinion a pivot 0.. One of said handles B has a flarwheel E, which latter is mounted upona pivot F carried by the handle A. Fixed to rotate with the pinion E is a ratchet wheel H, and I is a gear-wheel which is mounted u on the pivot F and carries a pawl J designe( to engage the teeth of the ratchet wheel II. The gear wheel I is in mesh with a pinion wheel K adapted to be driven in one direction and, sai wheel K has a fixed shaft N mounted in said handle A and to which the fan 0 is fastened. An auxiliary fan, designated by letter L and made of a suitable material, has arms L adapted to engage over the arms of the fan O, and said auxiliary fan has a central aperture Q adapted to receive Specification of Letters Patent. Application filed April s; ieos. Serial in. 427,419.

the shaft upon which the fan is mounted.

Patented Aug. 1a, 1908;

A spring T is coiled about'the pivot C and one end is fastened to the handle A While the other is fastened to the handle B in the man-- ner shown clearly in the drawings, the purpose of said spring being to normally return the handles to their starting position after having been pressed together by the hand of an operator.

The 0 era'tion of my fan will be readily un- I derstom and is as follows:The parts are normally held" by the spring in the position shown in Fig. 1. of the drawings. As the two handles are brought togetherunder tension of the spring T, a rotary movement through the gear mechanism shown is im )arted to the shaft carrying the fan wheel. y releasing the gri upon the handles, the spring will normally return the latter to their starting positions, the pawl riding idly over the ratchet teeth and, by successively gripping the handles, bringing together and releasing thesame, a continuous and rapid rotary movement will be imparted to the fan.

What I claim to be new is In combination with a stationary handle, a shaft mounted thereon, a fan j ournaled upon said shaft, a pivotal handle mounted upon the stationary handle and having a widened portion with a series of rack teeth along the end thereof, ear mechanism actuated by said rack teet for rotating the fan, a wire fastened at one end to the handle coiled about the pivot between the two handles and secured to the widened portion of the handle with gear teeth at' the end thereof, a reinforcing member mounted upon the fan shaft and having radial wings, fingers projecting from the edges of said wings. and adapted to engage over the wings of the frame, as shown and described.

In testimony whereof I hereunto alhx my signature in the presence of two witnesses.
